DETAILED DESCRIPTION

[0024] The utility model will be further described in combination with the embodiments and the drawings.

[0025] In an embodiment, as shown in Figures 1-7 Fig. 1, it is a high-strength inclined air pump hydraulic jack, which comprises a base 1 and a sleeve 2, a lifting oil cylinder 3, a manual pump 4 and an air pump 5 installed on the base 1. The lifting oil cylinder 3 is equipped with a lifting piston 6, and the sleeve 2 and the oil cylinder 3 directly form an oil storage chamber 8. The base 1 forms an oil inlet channel from the oil storage chamber 8 to the manual pump 4 and the air pump 5 respectively, an oil outlet channel from the manual pump 4 and the air pump 5 to the lifting oil cylinder 3 respectively, and an oil return channel from the lifting oil cylinder 3 to the oil storage chamber 8. The air pump 5 is installed obliquely on the base 1. This embodiment combines the functions of the manual pump 4 and the air pump 5, optimizes the lifting efficiency of the jack, and improves the flexibility and applicability of the equipment. Moreover, by obliquely installing the air pump 5 on the base 1, the required installation space of the air pump is effectively reduced, making the overall structure of the hydraulic jack more compact, especially suitable for limited space working environment.

[0026] In an embodiment, as shown in Figure 2 Fig. 2, the highest point of the air pump 5 is level with the lowest position of the top of the lifting piston 6. By further optimizing the relative height of the air pump 5, interference of the air pump 5 to the lifting piston 6 is avoided, ensuring the use of the jack at the lowest height, while also reducing the overall center of gravity, improving the safety and stability of the hydraulic jack.

[0027] In an embodiment, as shown in Figures 3-7 Fig. 3, the oil inlet channel from the oil storage chamber 8 to the air pump 5 has a parallel first oil channel 9 and a second oil channel 10, so a first one-way valve 11 is provided in the first oil channel 9, and a second one-way valve 12 is provided in the second oil channel 10. By designing parallel oil channels and one-way valves, the flow control and system reliability of the hydraulic jack are optimized, the safety and maintenance convenience in case of failure are improved, thereby significantly enhancing the working efficiency and safety of the equipment, meeting the application requirements of high load and high requirements.

[0028] In an embodiment, as shown in Figure 4 Fig. 4, the second one-way valve 12 adopts an adjustable cone valve, and is equipped with a safety sealing screw 13. By designing the adjustable cone valve, the flow control accuracy of the hydraulic jack and the safety and maintenance convenience of the system are improved. Not only the load capacity and stability of the equipment are enhanced, but also good adaptability is achieved, which can maintain high efficiency and reliability in various use scenarios, further meeting the needs of modern engineering and mechanical applications. The safety sealing screw 13 can effectively prevent the valve body from accidental loosening or failure under high pressure working conditions, thereby ensuring the overall safety of the hydraulic system. This design can effectively reduce the risk of leakage or failure of the hydraulic jack during work, improve the reliability of the equipment.

[0029] In an embodiment, as shown in Figures 1-3As shown, the top of the lifting piston 6 is mounted with a push plate 14, and the two sides of the push plate 14 are provided with traction springs 15 connected with the base 1. The push plate 14 significantly improves the supporting area and stability of the hydraulic jack, and improves the reliability of the equipment in heavy load and high intensity operation. The traction spring 15 plays a role in pulling back the push plate 14, so that the lifting piston 6 can be automatically reset after the backflow valve is opened.

[0030] In the embodiment, as shown in the figure, Figure 3 The outer sleeve 2 is concentrically installed with the lifting oil cylinder 3, and the top is provided with a top hat 7 for connection and fixation. The concentric installation of the outer sleeve 2 and the lifting oil cylinder 3 and the fixation design of the top hat 7 significantly improve the structural stability, load balance and sealing performance of the hydraulic jack, and simplify the assembly and maintenance process of the equipment, and improve the overall safety.

[0031] In the embodiment, as shown in the figure, Figures 1-3 The outer wall of the outer sleeve 2 is fixed with a handle 16, and the handle 16 and the air pump 5 are arranged on the two sides of the outer sleeve 2. The handle 16 is mainly convenient for carrying, and the handle 16 is arranged on the other side of the air pump 5, which has better lifting space and more reasonable gravity distribution, and is more labor-saving.

[0032] Obviously, the above-mentioned embodiments of the utility model are only for illustration of the utility model, and are not limited to the embodiments of the utility model. Other obvious changes or changes derived from the essential spirit of the utility model still belong to the protection scope of the utility model.
